Study on treatment and rehabilitation training of ligament injury of javelin throwers based on sports biomechanics

Abstract

Javelin throwing is very complicated. It is very important for athletes to master the javelin throwing technology. According to the investigation of athletes' ligament injuries, the preventive measures, treatment methods, rehabilitation methods and analysis were carried out by means of sports anatomy analysis. Through the analysis of Javelin throwers' injuries in sports, this paper uses the biomechanical analysis method to analyze the changes of data in the final exertion stage and the related reasons. The results showed that the injury constituent ratio of 50 national and elite javelin throwers was investigated. Obtain biomechanical indicators, focusing on the analysis of the possible sports injuries and the biomechanical characteristics of the javelin shots in the final stage of exertion. Studies have shown that athletes in the final stage of the force of the javelin shot, the left leg to stretch and stretch may be an important factor in the damage. Research on vulnerable sites should strengthen protective measures, such as strengthening the training of muscle strength in vulnerable parts and improving flexibility, and clarifying the relationship between injury and technical movement during exercise.
